摘要
A novel and simple method of dynamical roll measurement was proposed which uses a quarter waveplate as sensitivity part. The rolling and the orientation can be gotten by detecting the differential intensity of two light beams when the stage has a roll angle with respect to the reference base. According to the optic structure, the mathematical model was established by Jones matrix method. The theoretical analysis and the preliminary experimental results prove the effectivity and practicability. This performance is most advantageous in the long-distance and the high-precision measurement. Experimental results have shown that angular resolution is 0.05'; in a ±60'; range.
